SPECIFICATION forming part of Letters Patent No. 250,001, dated November 22, 1881,

Application filed J une 21, 1880. Renewed April 22, 1881. (No model.)

To all whom it may concern 7 Be it known that I, ABBOTT S. ROGERS, a citizen of the United States, residing at Salem, in the county of Essex and State of Massachusetts,haveinvented certain new and useful Improvements in Shoe-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it to appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. 1; This invention relates to improvements in boot and shoe presses for the purpose of uniting the previously-cemented outer sole to the cemented insole and overlapping edges of the upper, in the manufacture of what are known as compo boots.

Prior to my invention an elastic diaphragm has been actuated by a positive air or water pressure to force the sole to a boot or shoe, and to withdraw the gas or liquid as soon as 2 the sole has been permanently secured to the boot or shoe; also, a lasting-jack has been provided with an inflated bag or cushion secured to a frame in such position thatitforms a matrix which conforms to the last, in order 0 to last the boot or shoe when the lastis drawn down upon the same. The difference between my invention and such devices will be obvious from the following.

The invention is carried out as follows, reference being had to the accompanying drawings, on which- Figure 1 represents a plan view. Fig.2 represents a longitudinal section on theline AB, shown in Fig. 1 and Fig. 3 represents a crosssection on the line 0 1), also shown in Fig. 1.

Similarletters referto similarparts wherever they occur 011 the different parts of the drawings.

a to represent the frame of the machine, and

4 5 1) represents the up-and-dowumovable head, to which the vertical bars 0 o are attached. Said rods or bars 0 c are movable in guides in the frames a a, as shown, and attached in their lower ends to the adjustable pressurebar d, that is operated from the crank-shaft e 5 by means of the link f and elbow-jointed levers g g gg, the upper ends of the two latter being jointed to the under side of the table a.

h is a gear on the crank-shaft e, that is set in a rotary motion by means of the pinion t, that is loose on the driving-shaft k.

lis a coupling or clutch, laterally adjustable on the driving-shaft 7c in the usual manner, and operated by a treadle, m, and kneelever 11 in the ordinary way. 9

0 is the shoe-last, and p is the last holder or rest, attached in a suitable manner to the table a, as shown.

q is the boot or shoe upper, and r is the outer sole, as usual.

sis the hermetically-scaled and elastic air bag or receptacle for the purpose described, preferably located upside down in a socket or recess, 1), in the under side of the up-anddown-movable head, I), as shown, and t t are. 7 clamps or holding springs or bars for the purpose of holding the hermetically-sealed airbag 8 in its proper position to the movable head I), as shown.

What I wish to secure by Letters Patent, and claim, is-- In a boot or shoe pressfor uniting the cemented outer sole to the cemented inner sole and overlapping edges of the upper of a boot or shoe, the combination, with the movable head b, having the hermetically-sealed elastic bag 8 secured against its under side, of the last-holder p, secured upon a frame or bed and adapted to hold the last with the sole or bottom face thereof diametrically opposite the under side of the elastic bag, substantially as described.

In testimony whereof I have affixed my sig nature in presence of two witnesses.
